Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Given, 40% of the plants are homozygous recessive and White Flowers. So, the genotype frequency of WF = 0.4 Means, q^2=0.4 q=√0.4 q=0.6324 Recessive allele frequency = q = 0.6324 Dominant allele frequency = p = (1-0.6324) = 0.3676 Red flowers (RF) = Homozygous dominant = p^2 RF Individuals number in 14000 individuals = ( p^2 × 14000) = { (0.3676)^2 × 14000} = 1891.8166 ~ 1891 Pink flower (PF) = Heterozygous = 2pq PF Individuals number in 14000 individuals = (2pq × 14000) = { (2×0.3676×0.6324) × 14000 } = 6509.1667 ~ 6508 So the right option will be option 2 I'm attaching here my solved hand written copy. Hope it'll be beneficial. Feel free to ask me if you face trouble yet.
